Answer to Question 1

D

Answer to Question 2

A causal inference can only be supported when very specific causal evidence exists. Three critical pieces of causal evidence are:

(1) Temporal sequence - deals with the time order of events. The cause must occur before the effect.
(2) Concomitant variation - occurs when two events covary, meaning they vary systematically. This means that when a change in the cause occurs, a change in the outcome also is observed.
(3) Nonspurious association - means that any covariation between a cause and an effect is true and not simply due to some other variable.
